Police have found the woman who allegedly travelled to Northland with a woman who later tested positive for Covid-19.
In a media release on Monday evening, police say the woman was, "located at a West Auckland address this evening".
"The woman has been taken into custody under section 70 of the Health Act and will be transported to an MIQ facility," police say.
Police have not said if the woman has been tested for Covid-19 at this stage.
It comes after Northland was sent back into Alert Level 3 on Friday night after the woman's alleged travelling companion was confirmed as a positive case.
She first returned a "weak positive" Covid-19 test on Wednesday while in Whangārei. She was re-tested in Auckland on Thursday. That test came back positive.
Covid-19 Response Minister Chris Hipkins said the person travelled "extensively" while in Northland between October 2 and October 6.
"They are believed to have travelled around the region, including in Whangārei, Kamo, Paihia and Kawakawa, before returning to Auckland," he said.
"They have not been particularly forthcoming with their movements."
Comfort Hotel Flames in Whangārei, the Department of Conservation campsite at Uretiti, Pepe's Dairy in Onerahi, Z Kensington and BP Connect Wylies have been identified among the locations of interest in Northland.
Police and the Ministry of Health have been struggling to piece together the pairs movements as they have both been "uncooperative".
Earlier on Monday when asked about the woman who travelled with the Covid-19 case and is not co-operating, the Prime Minister said she felt just as “frustrated” by the person actions, as everyone else.
“This is an extraordinary set of circumstances where we have someone who may or may not be Covid positive, who has travelled with an individual, who we’ve identified but cannot locate, and they are refusing to cooperate.
“It is beyond irresponsible, it’s dangerous, we are using every tool and means we can to try and locate the individual.”
Police say they are continuing to investigate this matter and will be following up with the newly located individual.
